    CHANGING MY CAM

    in Gen I & II Chevy V8 Tech Board

    Posted

    Kevin, your right. The tranny gears, diff and stall was not totally matched for what I was looking for. I had two choices. change my diff amd torque converter, or change the cam to more properly match what I have. I didnt have the bucks to do the first choice so I hope I will see the difference Im looking for this way.

    Thanks for the input guys....Mike I envy you....I want a 383. However I am running 3"54 rear and 700R4 with 2800 stall. I need to get the BFgoodrich drag radials I guess. Im running 275 50 15 Nittos at the moment. I got the engine torn down today. Im waiting on the cam to come in. I hope to have it put together by Sunday....what a pain. Finally our track will open in May. Mike I may finally get to run it. Im looking to start another project so trying to decide 383 or 406. I suppose the 383 is the right choice for better support etc...

    Thanks guys I appreciate it. I needed a little more launch power and the previous cam was too big...XR282HR....this should work just fine, I was still running a 5 sec 0-60 with a sluggish launch. This should put me well in the 4s....ZFAN I am struggling...lol :D Thanks for the compliments guys...more updates soon. I put on a bre rear spoilers that compliments her well...

    NEED SOME INFO PLEASE!

    Well I still havent stinkin got a chance to run the Z down the strip. However, last night I met a group that went a little out of town on a farm road and made a couple of runs. I asked who the fastest guy was in this group and it was a 2003 Mitsubishi EVO Turbo AWD. So we lined up for a little less than an 1/8th mile. Another guy started us. I had a good launch and 3/4 thru first gear this EVO was dead even, I hear his blow off valve go PSSSST as he shifted to second (manual I suspect). At that point when I hit second gear 700R4 I instantly pulled about a car length on him and then proceeded to make ground. I got into the very top of third and it was over. I won by about 4 car lengths in about 800 feet or so. My question is WHAT DO THE EVOs run in the quarter? I am trying to gauge off of that. I know it would have been many more car lengths if we raced a 1/4 but Im still happy never the less. Lets just say that CorZette is now known by at least 100 people here in town after last night. They kept saying, THAT IS A FAST ASS NISSAN....everyone was cool...anyone know what the EVOs times are???? Thanks in advance

    Hey Mike! Damn, worse, sand storm advisory. It was raining all day Saturday then windy as hell so we didnt make it. man it sucks to have WALL raceway shut down here in San Angelo, its 10 miles away. Lubbock is open again on the coming Sunday. I will try again. My 750DP went caput on me. I ordered a new 650DP yesterday. I wanted to try the next step down to get better A/F mixture. man was this thing rich...it made my eyes water. Hopefully the 650 will work out better. More to come. One of these days we all have to meet at Ennis to hang out and race etc...thanks for inquiring.

    WHAT DIFF DO I HAVE????

    in Drivetrain

    Posted

    Thanks guys....one note to add, when I had my 3.90 diff on it would only take off spinning from one side, no slide from the back end. This diff always spins both tires on take off and slides the back end during lane changes if I punch it....Im happy as can be though :D

    WHAT DIFF DO I HAVE????

    in Drivetrain

    Posted

    Heres the deal. I have an R200 3.54 diff. It is apparently an LSD by the below pic. As you can see it is posi. This diff came with the car and I got the CV conversion done using the 280ZX shafts. How can this be? I thought that only the 300ZX 3.70 diff was LSD....Anyone care to explain this to me? :? Tim u out there?

    Octane Boosters

    in Gen I & II Chevy V8 Tech Board

    Posted

    Good info:

     

    Editor's note: I would NOT suggest that a person use the following fuel mixtures without considering the detrimental effects on your engine, vital engine components (O2 sensor, etc), and other potential damage. That said, the information is interesting.

    Original published in:

     

    GS-Xtra

    1213 Gornto Road

    Valdosta, GA 31602

    (912) 244-0577

     

    Editor: Richard Lasetter, president Gran Sport Club of America (GSCA)

     

    Formula #1 - Toluene

    R+M/2.........114

    Cost...........$2.50/gal

    Mixtures with 92 Octane Premium

    10%...........94.2 Octane

    20%...........96.4 Octane

    30%...........98.6 Octane

    Notes: Common ingredient in Octane Boosters in a can. 12-16 ounces will only raise octane 2-3 *points*, i.e. from 92 to 92.3. Often costs $3-5 for 12-16 ounces, when it can be purchased for less than $3/gal at chemical supply houses or paint stores.

     

    Formula #2 - Xylene

    R+M/2.........117

    Cost...........$2.75/gal

    Mixtures with 92 Octane Premium

    10%...........94.5 Octane

    20%...........97.0 Octane

    30%...........99.5 Octane

    Notes: Similar to Toluene. 12-16 ounces will only raise octane 2-3 *points*, i.e. from 92 to 92.3. Usually mixed with Toluene and advertised as *race formula*.

     

    Formula #3 - Methyl-tertiary-butyl-ether (MTBE)

    R+M/2.........118

    Cost...........$3.50/gal

    Mixtures with 92 Octane Premium

    10%...........94.6 Octane

    20%...........97.2 Octane

    30%...........99.8 Octane

    Notes: Oxygenate. Very common in octane booster products. Has lower BTU content than toluene or xylene, but oxygenate effect makes the gasoline burn better and produce more energy.

     

    Formula #4 - Methanol or Ethanol

    R+M/2.........101

    Cost...........$0.60 - $1.75/gal

    Mixtures with 92 Octane Premium

    10%...........94.3 Octane (Methanol)

    10%...........94.7 Octane (Ethanol)

    20%...........Not Recommended

    Notes: Methanol is wood alcohol. Ethanol is grain alcohol and found in Gasohol in 10% ratios. Both alcohols are mildly corrosive and will eat gas tank linings, rubber and aluminum if used in excessive ratios. Main ingredient in "Gas Dryers", combine with water.

     

    Formula #5 - Isopropyl Alcohol and Tertiary Butyl Alcohol

    R+M/2.........101

    Cost...........$0.60-$1.50/gal

    Mixtures with 92 Octane Premium

    10%...........94.5 Octane

    20%...........Not Recommended

    30%...........Not Recommended

     

    Notes: Similar to Methanol/Ethanol. Isopropyl Alcohol is simply rubbing alcohol.

     

    Sample Mixture

    To make your own octane booster, it is easiest to make up a large batch, and then bottle it up in "dosage-size" uses.

    Below is the basic formula of one of the popular octane booster products. To make eight 16 ounce bottles (128 oz = 1 gal):

     

    100 oz of toluene for octane boost

    25 oz of mineral spirits (cleaning agent)

    3 oz of transmission fluid (lubricating agent)

    This product is advertised as "octane booster with cleaning agent *and* lubricating agent!". Diesel fuel or kerosene can be substituted for mineral spirits and light turbine oil can be substituted for transmission fluid. Color can be added with petroleum dyes.

    CV SWAP QUESTION

    in Drivetrain

    Posted

    I have done the CV swap with the 280ZX adapters from Ross and love them, but if I switch to a 87 88 R200 from a 300ZX will the adapters accomodate the new axles or do I need to order a different adapter?
